Lubricating attachment for vehicle springs



R. L.. WBLLAMN LUBRICATING ATTACHMENT F'QR- VEHICLE SPRINGS Filed Oct. l2. 1921 readilyremoved therefrom if necessity.

should so require. Adapted to be situated between the outer 'surface o the spring 1l and the covering is a pair of longitudinellyv extending pads 8, each of which is preferably formed from an absorbent niaterial, such as felt, and are so situated as to tions 9 of the pads. .55v

engage with the upper surfaces of the sprin and also with the sides of the spring, eac upper portion othe pads being indicated by the numeral 9 and each side thereof by the numeral 10. These pads are adapted to extend substantially throughout the length of the covering 5 so'as to act in conjunction with the latter for the purpose of protecting the leaves or' said spring.l

ltwill be noted that the portions 9 ot' the pads 8 are relatively separatedl provide therebetween a longitudinally'eutending groove 11, and the outer and upper end of this groove is disposed -to communicate with a. filling-device 12. This device consists of a metallic strip 13, whose outer edges are disposed to engage ,with the upper surface 'of the yspring 1, and the intermediate portions thereof are bowed or bent so as to extend into the groove 11 between the portions 9ct the pads.` The central portion of the strip is provided with a threaded neck 14, which projects through an opening provided in the covering 5, and the outer end of the neck being equipped withv a threaded closure 15 which may be 'removed at will.

By this construction it will be manifest that the spring 1, when provided with the attachment comprising the present invention, may be lubricated and main-tained in perfect. working orde-r by removing the closurefl. This permits a quantity of a iiuid lubricant to be inserted into the groove 11,

the said lubricant flowing downwardly into' the groove by way of the intermediately bent ortions of the strip 13. It will be ob served that when the oil is received within the groove, lthe same will flow longitudinally throughout substantially the length of the groove, in order to be capable of quickly and uniformly engaging all parts of the. por- Since the pads are formed from an absorbent material, it follows that by a capillarity the lubricant will be drawn through the pads so as to saturate substantially the sides 10 thereof, the groove 11 allowing the sides 10. to be, uniormly` saturated when the lubricant is insorted into the spring. By the permeation of the sides 10 on the part of the lubricant, it will be apparent thatr the joints between the leaves 2 of the spring 1 may at all times be properly supplied With a, Sullfbl Quan Macnee relatively infrequent intervals the, placing of a lubricant within the Groove 11. lt will thus be seen that the attachment will require but a Vminimum of attention, and to all intents and purposes will be substantially automatic in operation.

iWhat is claimed is:

1. In a lubricating attaohmenttor vehilcle springs,y a dexible covering adapted to be detachably secured around the leaves of a vehicle spring, a pad formed from an absorbent material adapted to be positioned between the leaves of said' spring and said covering, said'y ad being formed to-include portionscapab e of. extendingparallelwith the sides and top' of said spr-mg; said pad being divided to provide a longitudinally extending lubricant groove on the top of -said spring, and means' cooperative with said coverino for permitting of the introduction of zflubrczmt4 into' said groove.

2. In a' lubricating attachment for vehicle springs, a ieniblefcoveri arranged to extend longitudinally of' an around'the leaves of a vehicle s ring, a pair of icc phads formed Jfrom an ali/sor nt material con ed between saidcovering and spring, said pads being situated to extend parallel with the sides and'top of said springtlie up er adjacent edges o said padsbeing re atively separated to provide-a longitudinally ex tending groove, and means for -permittin of the introduction of a lubricant into said groove. 3. In' a lubrcatin attachment for vehicle springs, a tlexibe covering adapted to surround and to eX-tendfglongitudinally of the leaves of a vehicle spring, means carried by the edges. of said covering to e'ect the fastening of the latter in'connectionwith said spring, a pair of spaced pads of an absorbent material adapted to' be confined between said covering and Vsaid. spring, said pads including portions arranged to extend parallel with the sides and top of said spring, the edges of saidj` pads extending along the top of said spring being relatively separated to provide a longitudinally i25- lliA introduction and retention of a lubricant Y within said groove;

' Il. In a. lubricating attachment for vehi# cle springs, a flexible covering arranged to Sui-round and to extend vlongitudinally of the leaves of a, vehicle 6B ing dis to engagewith the upper and si e edges of said spring 7:md having lis u pei* portion situated-1go form e longltu i- `spring2 a padding of 4ben Aan absorbent material posltloned' between' -said-coveriing; andspring, said padding be vmaeiuillic strip having an intermediately' t portion being disposed to be received B0 within -said groove and a fiiiing cap .car fied by said strip and' arranged to project through said covering. l
